Time Lapse Monitoring of Steam Injection Using High Resolution Seismic

In order to monitor the efficiency of steam injection into thin reservoirs filled with paraffinic oil in Fazenda Alvorada field was decided to use uncommon acquisition parameters to obtain high resolution 4D. Other aspect of this project was the large time interval between successive acquisitions what became a challenge to that project where we achieved frequencies as high as 100 hz, superior to the 30 hz observed on the conventional seismic and which made possible to monitor the steam movement.
